正極活物質、および、電池
Document Type and Number:
Japanese Patent JP6975919
Kind Code:
B2
Abstract:
A positive-electrode active material contains a lithium composite oxide, wherein the lithium composite oxide is a multiphase mixture having a first phase with a crystal structure belonging to a space group Fm-3m and a second phase with a crystal structure belonging to a space group other than the space group Fm-3m, and in an XRD pattern of the lithium composite oxide, the integrated intensity ratio I(18°-20°)/I(43°-46°)of a first maximum peak located at a diffraction angle 2θ in the range of 18 to 20 degrees to a second maximum peak located at a diffraction angle 2θ in the range of 43 to 46 degrees satisfies 0.05 ≤ I(18°-20°)/I(43°-46°)≤ 0.90.
